WordPress version 4.4 and above use a filter called pre_get_document_title() for a customzing title for each page, post, tag, category and more. For example, I can change 404 error title using this filter. One can use the wp_title() which was formerly deprecated in version 4.4 but was returned for compatibility reasons.
